natural selection
Gradualism isn't a prediction of natural selection, but of our understanding the mechanisms that produce reproductive variation. Natural selection makes predictions about allele frequencies in populations and reproductive fitness.
It's mainly mutations in the DNA and recombination of chromosomes that produce the genetic variation. Natural selection then favors those changes that give rise to greater reproductive success.
The answer of that qeustion is natural selection of which animals produce offspring.
Adaptation is the result of natural selection.

Natural selection
Non-random mating is otherwise known as sexual selection. Some see this as distinct from natural selection, but I think that sexual selection is merely a form of, or perhaps more a complication of natural selection. Selection, natural or sexual, is the effect that "guides" evolution, that allows evolution to produce populations suited to their environment.
Natural selection
Since natural selection also means the survival of the fittest, those organisms that produce antibiotics (against life) had a weapon to keep other organisms from taking their space that they needed to grow and reproduce.
